Product/AI App Builder
Describe the app. Get the whole product.
An AI agent builds your web and mobile app while you watch: accounts, a real database, payments, and an admin area, all working together and yours to keep.
How it works
Think it through, then build it.
Add a monthly / yearly switch to the pricing page and show the yearly saving.

- SubscriptionsStripe plans and trials, a customer portal, and usage limits
- EmailWelcome, verification, reset, and invite emails, ready to send

Each feature arrives working, with its pages, data, and settings, so the agent builds on it instead of writing it from scratch.
Your idea, running
See it working by the end of the day.
Describe the app, watch it come together, and change anything by pointing at it. It is yours to ship.
Point and change
Want it different? Point at it.
Show the change since last month under the total.
Click the parts of the dashboard. Each one attaches with the file and line it comes from, so the agent changes exactly that.

Background jobs
Shared underneath: one database, one sign-in, one design system, used by every part.
You stay in control
Checked, saved, and priced up front.
Checked every time
The agent checks its work after each change, and runs the full test suite whenever you ask.
Every version saved
Each change is kept with exactly what it changed. Go back to any version without losing the ones after it.
A price on each request
Choose the model, set a cap on what one request may spend, and see what each one cost. Or bring your own agent and keys.
Built from your design
It builds the app you designed, not a guess at it.
Ship it
A real link your testers can sign up on.
A live preview
A shareable link with its own database.
A pull request
Each version, on your GitHub repository.
Download it
The whole codebase, on every plan, any time.
Claim it
Move hosting and the database into your accounts.
Questions
About the App Builder.
Every plan includes the App Builder and the Website Builder. Compare plans
What is an AI app builder?
A tool where you describe the app you want and an AI agent writes it. In LiteSurface the agent works in a live sandbox: it edits a real codebase, checks its work after every change, and updates a preview while you watch, so you end up with a product you own rather than a locked-in prototype.
Can it build a full-stack app, not just screens?
Yes. Pick the parts your product needs: an API, a web app, an admin console, a marketing site, a mobile app, and background jobs. Sign-in, the database, email, and payments arrive wired together.
Can it build mobile apps?
Yes. The mobile app shares the API and sign-in with the web app. You publish it to the stores from your own Apple and Google accounts.
Do I own the code?
Yes. It is an ordinary repository. Download it or open a pull request on your GitHub repository at any time, on every plan, and take it anywhere.
Which AI models does it use, and what does a change cost?
You pick the model and effort for each request and set a spend cap per request. Each finished request shows what it cost at list prices. You can also bring your own agent over MCP or use your own provider keys.
How do I share the app before it is finished?
Publish any version as a deploy preview: a shareable link with its own database, so testers can sign up and use it. Claim a preview to move its hosting and database into your own accounts.

Describe it in a sentence, watch the agent build it, and keep everything.
